    [0003] ELECTRIC BIKE, ELECTRIC BIKE AND COUPLING PROCESS
    [0004]
    [0005] Technical sector
    [0006]
    [0007] The present invention relates to the structural formation of electric bicycles and, in particular, to the assembly of an electric battery for feeding a drive motor for propulsion in this type of bicycles, proposing a coupling between an electric battery and a frame of an electric bicycle that improves the characteristics of electric bicycles.
    [0008]
    [0009] State of the art
    [0010]
    [0011] The propulsion drive of electric bicycles is conventionally operated by an electric motor, which is powered for operation by an electric battery that is incorporated into the structural assembly of the bicycle, generally in its frame.
    [0012]
    [0013] To this end, a solution for incorporating the electric battery for feeding the propulsion drive motor in electric bicycles is to hold the electric battery with a mooring of any type in an external position on the bicycle frame; which has the disadvantage that the electric battery is exposed to easy manipulation and theft by outsiders, as well as to harmful influences of atmospheric agents.
    [0014]
    [0015] To eliminate this problem, solutions for the integration of the electric battery have been developed within one of the component elements of the bicycle frame; as the embodiment, for example, proposed by WO03 / 022671, which has an electric battery inside the diagonal tube of the bicycle frame, whereby the electric battery is protected and hidden, saving the inconveniences of the solutions of External arrangement of the electric battery on bicycles. However, this solution provides the electric battery in a fixed assembly within the diagonal tube of the panel, which makes it difficult to disassemble and replace the electric battery in case of maintenance, and for recharging the electric battery requires the transfer of the bicycle Complete as far as a recharge connection is available. In addition, access to the electric battery is made through the bottom of the diagonal tube of the frame, which forces the bicycle to turn in case of requiring access to the electric battery, with the consequent structural damage that the handlebar and saddle can suffer in the process.
    [0016]
    [0017] WO99 / 26837 proposes another solution for incorporating an electric battery into the diagonal tube of the frame of a bicycle, the electric battery being inserted by the bottom of the diagonal tube of the frame that converges on the bottom bracket of the bicycle, in where the electric battery housing is closed with a plug that fits into the mouth of the housing. This solution facilitates the removal of the electric battery, to take it to recharge to a recharging connection point, without having to move the bicycle to the place of recharging; but it has the disadvantage that, in order to determine the battery housing, it is necessary to move the mounting of the bicycle bottom bracket to a position above, or below, the confluence of the bars that make up the frame of the bicycle, whereby the bottom bracket is in a lower resistance assembly than in a conventional bicycle, in addition to the necessary structural modification of the bicycle for said assembly.
    [0018]
    [0019] European Patent EP 2913261, of the same holder as the present invention, proposed, to avoid the above drawbacks, an electric bicycle frame, comprising a diagonal tube with a defined housing inside where an electric battery assembly is inserted and in which the diagonal tube housing has an insertion mouth in its upper part for the introduction of the electric battery assembly.
    [0020]
    [0021] German Patent DE 102013 108313 proposes a solution in which there is also a housing in the frame of the bicycle, to accommodate the battery, the housing presenting a means of closure.
    [0022]
    [0023] WO2015 / 039785 also recommends a housing with a pivoting cover that has a closure, which in its operative position is fixed to the bicycle frame. The Chinese Utility Model CN203064153U also proposes a housing with a cover provided with closing means.
    [0024]
    [0025] In short, all these solutions that propose accommodation in the frame of the bicycle frame incorporate closure solutions of said housing, with a cover provided with blocking means, which entails a diversity of parts, complexity in assembly, points of deposit of dirt and maintenance problems.
    [0026]
    [0027] Object of the invention
    [0028]
    [0029] In accordance with the present invention, a coupling between an electric battery and an electric bicycle frame is proposed in which the electric battery is inserted into a defined housing in a diagonal tube of the electric bicycle frame, where the electric battery has in at least one of its minor faces a conicity in reciprocal correspondence with a conicity that presents at least one of the minor faces of the housing; so that when the electric battery is introduced into the housing, the smaller faces in conicity enter into reciprocal correspondence, establishing a dovetail coupling between the electric battery and the diagonal tube of the bicycle frame.
    [0030]
    [0031] In addition, at the base of the battery and at the base of the diagonal tube housing of the frame of the bicycle that is to be faced with that base, there are means that allow to establish a reciprocal coupling type tongue and groove that allows the guided radial rotation of the electric battery with respect to the housing, said means being, for example, a cavity and a pivot that can be accommodated in said cavity.
    [0032]
    [0033] With this solution of inverted conical housing and configuration in correspondence of the battery, unlike the current solutions, the vertical vibration movements of the bicycle are absorbed in its daily use, preventing the battery from moving vertically and avoiding losing the connections . Therefore, battery adjustment problems are solved vertically.
    [0034]
    [0035] On the other hand, the way to insert the battery sideways and fix it by means of a rotation, allows the upper tube of the bicycle frame to be brought closer to the diagonal tube, as long as the longitudinal dimension or height of the pivot pivot allows. With this side mount instead of an upwardly mounted mount as in most conventional solutions, in which the battery is pulled from one end up, the risk of touching the battery in the upper tube is suppressed.
    [0036]
    [0037] In short, it is a montage in which the space between the space is maximized diagonal tube and the upper tube of the bicycle frame.
    [0038]
    [0039] With this assembly the battery is secured against movements in the vertical direction, which are the most common to support on a bicycle when jumping, overcoming obstacles, etc. However, it has been provided that the electric battery and the housing comprise engaging means that prevent the involuntary radial rotation of the electric battery once mounted in the housing, said means of being able to be pins that project from the smaller faces of the electric battery and receptacles defined in the smaller faces of the housing, the pins being inserted in said receptacles.
    [0040]
    [0041] Likewise, the invention also proposes an electric bicycle that incorporates a coupling as indicated.
    [0042]
    [0043] In addition, the invention also proposes a coupling process between the electric battery and the corresponding diagonal tube of the bicycle frame, which comprises the following phases:
    [0044]
    [0045] - arrangement of the radially rotated electric battery with respect to the diagonal tube to be accommodated.
    [0046]
    [0047] - approach of the electric battery to the diagonal tube until the coupling means reciprocally correspond.
    [0048]
    [0049] - rotation of the electric battery to align it with the diagonal tube so that the smaller faces enter into correspondence.
    [0050]
    [0051] - fixing the electric battery in its mounting position.
    [0052]
    [0053] A coupling solution for the electric battery is thus achieved which is very safe, which does not require complementary elements or means of coupling or closing, so that its application is greatly simplified, which allows a simple assembly and disassembly of the battery and that it allows both the electric battery and the diagonal tube of the frame where it is housed to be able to present a uniform surface in continuity that prevents the deposit of dirt.

    [0073]
    [0074] Detailed description of the invention
    [0075]
    [0076] The present invention relates to the coupling of an electric battery (1) of a bicycle electrical in a housing (2) of the corresponding tube of the frame of said bicycle, preferably a diagonal tube (3). The invention also relates to the bicycle itself that presents this coupling and the process for making this coupling.
    [0077]
    [0078] The housing (2) is open on its major faces and comprises a base (2.2) and two minor faces (2.1). In accordance with the present invention, at least one of the two opposing smaller faces (2.1) is configured with an inverted taper as a half dovetail.
    [0079]
    [0080] For its part, the electric battery (1) comprises a base (1.2) and two smaller side faces (1.1). Corresponding to the configuration of the housing (2), at least one of said minor faces (1.1) has an inverted conicity configuration.
    [0081]
    [0082] An example of a practical, non-limiting embodiment is shown in Figures 3 to 6, according to which the two minor faces (2.1) of the housing (2) have an inverted taper and, in reciprocity with this configuration, also the two minor faces ( 1.1) of the electric battery (1) offer the same configuration in inverted conicity, which allows, as will be described in more detail later, a dovetail coupling between the electric battery (1) and the smaller faces (2.1) of the housing (2) of the diagonal tube (3) of the electric bicycle frame.
    [0083]
    [0084] In the base (1.2) of the electric battery (1) and in the base (2.2) the housing (2) there are means that allow to establish a reciprocal coupling type tongue and groove that allows the guided radial rotation of the electric battery (1) with respect to of accommodation (2).
    [0085]
    [0086] Preferably, as shown in Figure 3, a central pivot (6) protrudes from the base (1.2) of the electric battery (1); while at the base (2.2) of the housing (2) there is a central cavity (7) in correspondence with said pivot (6).
    [0087]
    [0088] With the electric battery (1) arranged rotated radially with respect to the housing (2), as shown in Figure 4, it is possible to approximate the electric battery (1) to the housing (2) of the diagonal tube (3) of the frame the bicycle, until the pivot (6) penetrates the cavity (7). At that time, the electric battery (1) can be rotated, as shown in figure 4; so that the electric battery (1) rotates radially around an axis (5), until it is aligned with the diagonal tube (3), as shown in figures 5 and 6. Upon reaching this position, the two smaller faces (1.1) of the electric battery (1) correspond to the two smaller faces (2.1) of the housing (2), establishing a coupling between the battery electric (1) and the diagonal tube (3) that prevents the displacement of the electric battery (1) in the direction of the shaft (5).
    [0089]
    [0090] The electric battery (1) and the housing (2) have hooking means that prevent the involuntary radial rotation of the electric battery (1), once coupled in the housing (2).
    [0091]
    [0092] Preferably, said hooking means may be pins (9) projecting from the smaller faces (1.1) of the electric battery (1) and receptacles (10) defined on the smaller faces (2.1) of the housing (2). ), the pins (9) being inserted into said receptacles (10). Thus, when the electric battery (1) is mounted, as shown in Figure 5, the pins (9) penetrate the receptacles (10), giving rise to a hitch that prevents the involuntary radial movement of the electric battery (1) necessary for disassembly, if not the user acts on the electric battery (1) forcing that hitch to be released.
    [0093]
    [0094] Also, instead of two pins (9) and two receptacles (10), there could be only one pin (9) and one receptacle (10) in correspondence, as long as sufficient radial retention of the electric battery (1) is achieved. in your accommodation (2).
    [0095]
    [0096] In addition, the coupling means could be any other elements that cause a conventional coupling, such as elements that cause the coupling by elastic clipping. For example, these alternative coupling means could be located in the bases (1.2) and (2.2) of the electric battery (1) and of the housing (2) respectively; or in the pivot (6) and in the cavity (7) or in any other location that, by friction, elastic clipping or similar conventional solution establishes the retention of the electric battery (1) in the housing (2).
    [0097]
    [0098] It is envisaged that in addition to this hook of the electric battery (1), the coupling assembly is provided with a conventional lock not shown, to avoid that when the bicycle is parked having the electric battery mounted (1) and the user is not next to your bicycle, a third party can release and take the electric battery (1).
    [0099]
    [0100] Also, in these figures 3 to 6 an example of practical embodiment has been represented, according to which the two smaller faces (1.1) of the electric battery (1) and the two smaller faces (2.1) of the housing (2) have an inverted conicity to give rise to a dovetail coupling. However, said inverted taper could occur only on one of the minor faces (1.1) and on its corresponding minor face (2.1), as shown in Figures 7 to 9.
    [0101]
    [0102] In this case, the coupling would be in half dovetail. Moreover, as can be seen in Figure 7, it is foreseen that not the entire surface of the smaller faces (1.1) and (2.1) has to be in conicity, but that the conicity can be combined with straight parts (1.3) and (2.3) or even with other configurations.
    [0103]
    [0104] Figures 7 to 9 show how the assembly process of the electric battery (1) in the diagonal tube (3) of the bicycle frame is carried out. Thus, in figure 7 it is shown how the electric battery (1) is approached towards the diagonal tube (3), the electric battery (1) being rotated with respect to the diagonal tube (3). Figure 8 shows how, once the insertion of the pivot (6) into the cavity (7) has occurred, the electric battery (1) can be turned until it reaches the arrangement of Figure 9, in which the Electric battery (1) is already aligned with the diagonal tube (3) and mounted in the housing (2) of said diagonal tube (3).
    [0105]
    [0106] With this assembly, the electric battery (1) cannot leave its housing (2) in the direction of the axle (5) which is where the most important efforts to bear are produced, due to the jumps that a bicycle can give, vibrations, overcoming obstacles, etc.
    [0107]
    [0108] Also in this figure 7 it can be seen how the electric battery (1) and the diagonal tube (3) remain in perfect continuity, with a uniform outer surface and no gaps in which dirt can be deposited.
    [0109]
    [0110] Figure 1 shows the electric battery (1) already mounted on the frame of a bicycle, to be able to appreciate that the distance between the diagonal tube (3) and the lateral assembly made of the electric battery (1). an upper tube (4) of the bicycle frame can be minimal, without the risk that the electric battery (1) collides with the tube (4) in the assembly or disassembly of the electric battery (1). Practically this separation would only be limited by the length of the pivot (6).
    [0111] Figure 2 shows the electric battery (1) mounted on a bicycle frame that does not include an upper tube (4).
